Prolonged exposure to high levels of infrared radiation could lead to burns and cause eye problems, including cornea and retina damage, cataracts and injuries to the eye lens. In addition, infrared radiation can cause pain to the skin of a person in close contact with it.Know More
Most infrared radiation is not visible and may affect a person without his knowledge. Similarly, some radiation is neither hot nor colored, making them difficult for people to detect and avoid.
In the electromagnetic spectrum, infrared rays are just below visible red light. Many objects, including lamps, flames, stars and other warm items, emit these rays. They are most commonly used in mobile phones, in remote controls for TV sets and in other short-range communication devices. In addition, physiotherapists use infrared technology to help the healing of athletes' injuries.
Modern weapons have infrared detectors that are designed to spot targets, particularly at night. Although occasional exposure to these rays is not enough to cause danger, everyday contact can cause long-term health problems. Employees working for companies involved in the mass production of lasers and heat lamps have a higher risk of experiencing adverse effects due to exposure. These rays can disrupt body cells, penetrate DNA and cause cancer. Those who are vulnerable are advised to wear protective gear.Learn more about Optics & Waves
According to the Eye Care Office of Ofner, Neale and Fleming, cataracts of the eye create a clouding of the lens inside the eye, behind the pupil or iris (the colored portion of the eye), that is often mistaken for a film over the eye. Cataracts are a common aspect to the aging process. Early signs of cataracts include decreased distance vision and decreased vision while reading.Full Answer >
Cat cataracts can be congenital, can develop naturally during the aging process, can be caused by poor nutrition or can occur due to traumatic eye injuries. A taurine deficiency is a common cause for cat cataracts, usually in both eyes. Cats may develop cataracts as a result of physical trauma or underlying medical conditions. PetWave states that diabetes does not usually cause cat cataracts, unlike with dogs.Full Answer >
Cataracts are removed after the eye surgeon makes an incision in the patient's cornea and then carefully removes the clouded lens. Before surgery, topical medications are used to dilate the pupil and numb the eye. The patient may also be sedated.Full Answer >
Astigmatism is a condition that causes blurred vision when the lens or cornea of an eye has an irregular surface contour, according to Mayo Clinic. Rather than having a consistently smooth curvature, an astigmatic lens or cornea has abnormal curves and flattened areas, changing how the eye processes light.Full Answer >
